DP is a Linear Response TDDFT code,
in Frequency-Reciprocal and Frequency-Real space, on a Plane Waves basis set.
- Definition: Linear Response Time-Dependent Density-Functional Theory (LR-TDDFT) code
in Frequency Reciprocal (k-ω)
space on a Plane Waves (PW) basis set. Some quantities (the Kohn-Sham polarizability and the exchange correlation kernel) are calculated in Real (r) space
- Purpose: Dielectric and Optical Spectroscopy
(Optical Absorption, Reflectivity,
Refraction Indices, EELS, IXSS, CIXS, ...).
- Systems: Bulk Solids, Surfaces, Clusters, Molecules, Atoms
(through supercells) made of Insulator, Semiconductor
and Metal elements.
- Approximations: RPA, ALDA, GW-RPA, LRC,
non-local kernels, ...,
with and without LF (Local Fields).
